Hi Keira,
Something will work out, takes a bit of patience though. I certainly understand what you're going through. Being dead is pointless, because there's nothing to do. Might as well live, and enjoy the things that make you happy. I learned to shut the world off. When I'm in public, I wear my headphones and play my music, and I go to peaceful places where no-one judges me. Solitude and aloneness can be really beneficial. Simply remind yourself that no-one cares more about you than you do, because everyone else is worrying about themselves. Sounds super dark, but it's actually the truth and it is enlightening: it frees you from everything, because it means that no-one cares about your mistakes too. So, all that's left is potential and opportunity.
